dc.description.abstract | Los objetivos de esta investigación fueron determinar la distribución espacial e identificar los factores de riesgo asociados a la leptospirosis bovina en el estado de Veracruz, México. Se obtuvieron muestras de sangre de 3,454 bovinos de 54 municipios de las regiones Norte, Centro y Sur del estado, de febrero 2008 a diciembre de 2011. Los sueros se analizaron por medio de la técnica de aglutinación microscópica utilizando 12 serovariedades de Leptospira interrogans, se estimaron las seroprevalencias y los factores de riesgo. La seroprevalencia general fue del 3.9%; sin embargo, entre municipios varió de 0 y 44%. La mayoría de las UP con casos positivos se encontraron en la zona centro de Veracruz, y en los municipios de Cuitláhuac, Papantla, Tlacotalpan y Tlalixcoyan se incrementa el riesgo de presentar leptospirosis bovina, también el que las perras y gatas tengan acceso a parir en los comederos incrementa el riesgo de presentar la enfermedad. Se concluye que la leptospirosis bovina está presente en el estado de Veracruz con mayor distribución en la zona centro del estado, y las serovariedades más prevalentes fueron Hardjo, Lai Lai, Canicola, Tarassovi y Pyrogenes. _______________ SPATIAL DISTRIBUTION AND RISK FACTORS ASSOCIATED WITH BOVINE LEPTOSPIROSIS IN VERACRUZ, MEXICO. ABSTRACT: The objectives of this investigation were to determine the spatial distribution and identify the risk factors associated with bovine leptospirosis in the state of Veracruz, Mexico. During February 2008 to December 2011, blood samples were collected from 3,454 cows from 54 municipalities in the northern, central and southern regions of the state. The sera were analyzed using microscopic agglutination tests and included 12 serovars of Leptospira interrogans. General and specific seroprevalence were estimated, and risk factors were identified. The overall seroprevalence was 3.9% and varied between 0 and 44% among municipalities. Most of the positive sites were found in central Veracruz. The risk factors associated with leptospirosis in the state were municipalities (Cuitlahuac, Papantla, Tlacotalpan, and Tlalixcoyan), and dogs and cats birthing in feeding troughs. Bovine leptospirosis is present in the state of Veracruz with most of its distribution in the central part of the state. The most prevalent serovars were Hardjo, Lai Lai, Canicola, Tarassovi and Pyrogenes. | en_US |
